Main Features

Our Key2roam Hub processes all roaming traffic, including 2G, 3G, 4G, LTE, VoLTE, CAMEL. We have also recently completed new trials, meaning that Key2roam Hub can now process 5G roaming traffic.

Alongside our more traditional MNO customer base, we are keeping up with all new trends and technologies in the market, and are currently onboarding new IoT/M2M (Machine-to-Machine) players as Key2roam Hub members.
We are proud to be pioneers in the roaming industry once again, and are paving the way to ensure Borderless Connectivity is already a reality.

Members have the option of launching LTE and VoLTE data roaming relations with the same simplicity and principles as 2G and 3G data roaming, which helps to ensure a faster time to market for deployment. The process is fully managed by one of our Roaming Coordinators, and includes organising the implementation, testing, launch letter and quality monitoring.

At Comfone, we pride ourselves on having great relationships with Operators around the world. As a result of this personal relationship, coupled with our unmatched expertise in the industry, we have developed our Roaming Relations Management service.

We are perfectly placed to manage direct roaming relations, so you can increase roaming coverage without compromising resources. Comfone provides a smart solution for anyone looking for complete Roaming Management delivered by an experience team that can quickly launch new operators and services.

We consider our Key2roam Hub customers to be part of an elite club. Above all, we are always looking for new ways to provide additional service benefits.
